Description

This specification relates to a tray-type component supply device that supplies components using trays.

Board-related processing machines that produce board products with many components mounted thereon include solder printers, component mounting machines, reflow machines, and board inspection machines. It is common to arrange these board-related processing machines in a row to form a board production line. Among these, component mounting machines may be equipped with a component supply device that uses a tray on which components are arranged. In general, a tray-type component supply device holds multiple trays and supplies multiple types of components by replacing the trays when components are consumed. Technical examples of this type of tray-type component supply device are disclosed in Patent Documents 1 and 2.

Patent Document 1 discloses a component mounting system that replenishes tray parts using a resupply unit mounted on a traveling body that travels between a component storage facility and multiple component mounting machines. In this system, a tray feed mechanism transfers trays on which tray parts are arranged between a magazine on the traveling body side and a magazine on the component mounting machine side. This makes it possible to automatically replenish and collect trays, and automatically and efficiently replenish required parts.

The chip supply device in Patent Document 2 includes a magazine that stores multiple trays arranged vertically, a holder that suspends and holds the magazine, and a means for moving the holder up and down, and ensures a space below the magazine for a cart to move in and out. This allows an operator to use the cart to replace the magazine.

However, the technology in Patent Document 1 automatically transfers trays one by one, and cannot replace multiple trays housed in a magazine all at once. This makes the replacement operation complicated and time-consuming when replacing multiple trays, such as when changing the setup to change the type of boards being produced. In contrast, the technology in Patent Document 2 can replace magazines all at once, but since the replacement work is done manually, automation has not been achieved.

The problem to be solved in this specification is to provide a tray-type component supply device that can automatically replace a magazine that contains multiple trays.

This specification discloses a tray-type component supply device that includes an apparatus main body, a magazine that is detachably held in the apparatus main body and that stores multiple trays, on which multiple components are arranged, arranged one above the other, a shuttle mechanism that pulls out one of the trays from the magazine to supply the components, a lifting mechanism that raises and lowers the magazine or the shuttle mechanism to select the tray that the shuttle mechanism pulls out, and an automatic exchange unit that exchanges the magazine that is retrieved from the apparatus main body with the magazine that is replenished to the apparatus main body.

According to the tray-type component supply device disclosed in this specification, the automatic replacement unit replaces the magazine that is retrieved from the device body with the magazine that is replenished to the device body, so that magazines that contain multiple trays can be replaced automatically.

FIG. 11 is a diagram showing an operation flow when the tray-type component supplying device replaces the automatic magazine.

1. Configuration of the magazines (3A, 3M) of the tray-type component supplying device 1 of the embodiment The configuration of the tray-type component supplying device 1 of the embodiment will be described with reference to the device configuration diagrams of Figures 1 to 3 and the control configuration diagrams of Figures 4 and 5. In the plan view of Figure 1, the front-rear and left-right directions common to the component mounting machine 9 and the tray-type component supplying device 1 are defined for convenience. The outline of the component mounting machine 9 is shown in Figures 1 to 3, and the mounting head 91 and suction nozzle 92 equipped to the component mounting machine 9 are shown in Figures 2 and 3.

The tray type component supplying device 1 is mounted in front of the component mounting machine 9. The tray type component supplying device 1 supplies components to the component mounting machine 9 using a tray Ty on which a plurality of components are arranged. The tray type component supplying device 1 is composed of a device main body 2, an automatic magazine 3A, a manual magazine 3M, a shuttle mechanism 4, a lifting mechanism 5 (see FIG. 4), an automatic magazine exchange unit 6A, a feeder device 3F, an automatic feeder exchange unit 6F, two height detection units 7A and 7F, a height adjustment unit 7J, and a control device 8 (see FIG. 4 and FIG. 5).

The device main body 2 is composed of a main body case 21, an insertion section 25, a lower holding table 26, and an upper holding table 28. The main body case 21 is formed in a vertically long rectangular shape. The main body case 21 is disposed close to the front edge of the component mounting machine 9. An automatic exchange window 22 larger than the size of the automatic magazine 3A is opened toward the bottom of the front of the main body case 21. An openable maintenance door 23 larger than the size of the manual magazine 3M is provided toward the top of the front of the main body case 21. A pull-out window 24 larger than the size of the tray Ty is opened at approximately the middle height of the rear of the main body case 21.

The insertion section 25 is provided on the rear surface of the main body case 21. The insertion section 25 is inserted inside the component mounting machine 9. The insertion section 25 consists of a shuttle support section 251 and a feeder holding section 252. The shuttle support section 251 is a horizontally arranged rectangular plate-shaped member. The shuttle support section 251 is located to the left of the component mounting machine 9 and slightly lower than the drawer window 24. The feeder holding section 252 is a horizontally arranged rectangular plate-shaped member. The feeder holding section 252 is located to the right of the component mounting machine 9 and higher than the shuttle support section 251.

The lower holding table 26 is arranged inside the main case 21 so that it can rise and fall. The lower holding table 26 is a rectangular, thick plate-like member. The lower holding table 26 has transfer rollers 27 arranged in a row in the front-to-rear and left-to-right directions. The upper holding table 28 is arranged above the lower holding table 26 inside the main case 21 so that it can rise and fall. The upper holding table 28 is a rectangular, thick plate-like member.

The automatic magazine 3A is formed in a box shape with a height less than half that of the main body case 21. The automatic magazine 3A is removably held on the upper side of the lower holding table 26. The load of the held automatic magazine 3A is supported by the transfer roller 27. The transfer roller 27 is one embodiment of the main body side magazine drive unit that transfers the automatic magazine 3A by rotating with the automatic magazine 3A placed on it.

Inside the automatic magazine 3A, multiple holding shelves 31 are arranged vertically. Each holding shelf 31 stores a tray Ty. Each tray Ty has multiple parts arranged in a two-dimensional lattice pattern. The rear of the automatic magazine 3A is open, allowing the tray Ty to be pulled out rearward. Note that a tray pallet (not shown) on which the tray Ty is placed may be stored in each holding shelf 31, allowing the tray Ty and tray pallet to be pulled out together.

The automatic magazine 3A is adjusted in height so that it faces the automatic exchange window 22. The automatic magazine 3A is transported to the front of the lower holding table 26 by the reverse rotation of the transport rollers 27, and passes through the automatic exchange window 22 toward the front. This allows the automatic magazine 3A to be removed from the device main body 2. The automatic magazine 3A is also transported from the front to the lower holding table 26, passing through the automatic exchange window 22, by the forward rotation of the transport rollers 27. This allows the automatic magazine 3A to be replenished to the device main body 2.

The manual magazine 3M, like the automatic magazine 3A, is formed in a box shape with a height less than half that of the main body case 21. The manual magazine 3M is held on the upper side of the upper holding table 28. Inside the manual magazine 3M, multiple holding shelves 33 are arranged vertically. Each holding shelf 33 stores a tray Ty. Each tray Ty has multiple parts arranged in a two-dimensional lattice pattern. Note that the manual magazine 3M and the automatic magazine 3A may be of the same shape.

The rear of the manual magazine 3M is open, allowing the tray Ty to be pulled out rearward. The height position of the manual magazine 3M can be adjusted so that it faces the maintenance door 23. The front of the manual magazine 3M is open, and maintenance is performed through the maintenance door 23. For example, an operator can replenish parts by replacing the tray Ty through the maintenance door 23, or inspect the inside of the manual magazine 3M. Furthermore, the operator can also replace the entire manual magazine 3M.

The lifting mechanism 5 raises and lowers the automatic magazine 3A and the manual magazine 3M independently. The lifting mechanism 5 is controlled to avoid collision between the automatic magazine 3A and the manual magazine 3M. The lifting mechanism 5 plays a role in selecting the tray Ty to be drawn out from the drawing window 24. As shown in FIG. 4, the lifting mechanism 5 includes a first lifting mechanism 51 that drives the automatic magazine 3A to rise and fall together with the lower holding table 26, and a second lifting mechanism 52 that drives the manual magazine 3M to rise and fall together with the upper holding table 28. An example of the first lifting mechanism 51 and the second lifting mechanism 52 is a ball screw feed mechanism driven by a motor.

The shuttle mechanism 4 is provided above the shuttle support portion 251. The shuttle mechanism 4 can pull out any of the trays Ty from the automatic magazine 3A or the manual magazine 3M to supply parts. The shuttle mechanism 4 has a locking portion that locks a locking portion provided on the tray Ty or the tray pallet to pull it out of the main case 21 or to return it to the main case 21. In FIG. 2, the topmost tray Ty of the manual magazine 3M has been pulled out. The suction nozzle 92 descends toward the pulled out tray Ty and sucks up the parts by supplying negative pressure.

The automatic magazine exchange unit 6A exchanges the automatic magazine 3A retrieved from the device main body 2 with the automatic magazine 3A to be replenished to the device main body 2. As shown in FIG. 2, the automatic magazine exchange unit 6A is equipped with running wheels 6A1 equivalent to a running unit, and is configured in the form of an unmanned guided vehicle. The running wheels 6A1 run along a running path 62 leading to the parts warehouse 63. This allows the automatic magazine exchange unit 6A to run back and forth between the parts warehouse 63 and the part mounting machine 9. Position markers for controlling the running position of the automatic magazine exchange unit 6A are appropriately placed near the running path 62. The automatic magazine exchange unit 6A detects the position markers and recognizes its current position.

Two storage sections 6A5 for storing automatic magazines 3A are provided above the automatic magazine changing section 6A. The automatic magazine 3A to be replenished is placed in one of the storage sections 6A5. The automatic magazine 3A to be retrieved is placed in the other storage section 6A5. In FIG. 1, the automatic magazine 3A to be replenished is shown in solid lines, and the automatic magazine 3A to be retrieved is shown in dashed lines. This is not limited to the above, and the automatic magazine changing section 6A may run with two automatic magazines 3A stored, or may run without storing any automatic magazines 3A.

The storage section 6A5 has transfer rollers 6A6 arranged in a row in the front-rear and left-right directions. The load of the automatic magazine 3A stored in the storage section 6A5 is supported by the transfer rollers 6A6. The transfer rollers 6A6 are one embodiment of a replacement side magazine drive section that transfers the automatic magazine 3A by rotating with the automatic magazine 3A placed on it. The transfer rollers 6A6 work together with the transfer rollers 27 on the device main body 2 side to transfer the automatic magazine 3A.

In more detail, prior to transfer, the transfer roller 6A6 and the transfer roller 27 are arranged side by side in the front-to-rear direction. The automatic magazine 3A to be replenished is directed backward from the storage section 6A5 by the forward rotation of the transfer roller 6A6. Furthermore, the automatic magazine 3A to be replenished is replenished into the device body 2 through the automatic exchange window 22 by the forward rotation of the transfer roller 27. Furthermore, the automatic magazine 3A to be collected is removed from the inside of the device body 2 through the automatic exchange window 22 by the reverse rotation of the transfer roller 27. Furthermore, the automatic magazine 3A to be collected is stored in the storage section 6A5 by the reverse rotation of the transfer roller 6A6.

The height relationship between the device body 2 and the automatic magazine exchange unit 6A may change due to the automatic magazine exchange unit 6A traveling back and forth between the parts warehouse 63 and the parts mounting machine 9. For example, the height position of the storage unit 6A5 may change due to changes in the conditions of the travel path 62 and the floor surface F, or due to individual differences between the multiple automatic magazine exchange units 6A. To address this, a height detection unit 7A is provided, and the first lifting mechanism 51 functions as a height adjustment unit.

The height detection unit 7A is disposed below the automatic exchange window 22 on the front side of the main body case 21. The height detection unit 7A detects the height of the storage unit 6A5 which it is generally directly facing. An example of the height detection unit 7A is a detection type sensor that reads a linear scale attached so as to extend in the vertical direction of the storage unit 6A5, but is not limited to this.

The first lifting mechanism 51, which corresponds to the height adjustment unit, adjusts the height of the automatic magazine 3A to be retrieved, i.e., the height position of the lower holding table 26, based on the detected height of the storage unit 6A5. As a result, the height of the bottom end of the automatic magazine 3A to be retrieved matches the height of the top of the storage unit 6A5. The first lifting mechanism 51 also adjusts its own height, i.e., the height position of the lower holding table 26, to match the automatic magazine 3A to be replenished, based on the detected height of the storage unit 6A5. As a result, the height of the bottom end of the automatic magazine 3A to be replenished matches the height of the top of the lower holding table 26. Therefore, there is no difference in height when the automatic magazine 3A is transferred, realizing a smooth replacement operation.

2. Configuration of the feeder device 3F of the tray-type component supply device 1 The feeder device 3F is disposed above the feeder holding portion 252, and is positioned by a locking mechanism (not shown). In this embodiment, the feeder device 3F is composed of a feeder pallet (not shown) and multiple feeders. More specifically, the plate-shaped feeder pallet is formed with multiple slots extending in the front-rear direction. A feeder is fitted into each slot. Each feeder supplies the components by unwinding a carrier tape that holds multiple components. However, the feeder device 3F may be composed of a single feeder.

The feeder holding section 252 has transfer rollers 29 arranged in a row in the front-rear and left-right directions. The load of the feeder device 3F held by the feeder holding section 252 is supported by the transfer rollers 29. The transfer rollers 29 are one embodiment of the main body side feeder drive section that rotates with the feeder device 3F placed on it to transfer the feeder device 3F.

The automatic feeder exchange unit 6F exchanges the feeder device 3F that is collected from the main body 2 with the feeder device 3F that is replenished to the main body 2. As shown in FIG. 3, the automatic feeder exchange unit 6F is configured in the form of an unmanned guided vehicle, equipped with running wheels 6F1 that correspond to a running unit. The running wheels 6F1 run along a running path 62 that continues to the parts warehouse 63, so that the automatic feeder exchange unit 6F runs back and forth between the parts warehouse 63 and the parts mounting machine 9. The automatic feeder exchange unit 6F may have the same shape as the automatic magazine exchange unit 6A, or a different shape.

The parts warehouse 63 stores at least one of the feeder devices 3F and carrier tapes. Furthermore, the parts warehouse 63 stores at least one of the automatic magazines 3A and trays Ty. Therefore, an operator can perform preparation work for the automatic magazines 3A and feeder devices 3F to be replenished within the parts warehouse 63. The automatic feeder exchange unit 6F transports the prepared feeder devices 3F and replenishes them in the device main body 2. The automatic feeder exchange unit 6F also transports the collected feeder devices 3F and takes them back to the parts warehouse 63.

Similarly, the automatic magazine exchange unit 6A transports the prepared automatic magazine 3A and supplies it to the device main body 2. The automatic magazine exchange unit 6A also transports the collected automatic magazine 3A and takes it back to the parts warehouse 63. Note that the parts warehouse 63 and the travel path 62 are common to the automatic feeder exchange unit 6F and the automatic magazine exchange unit 6A, but may be provided separately.

Two storage sections 6F5 for storing feeder devices 3F are provided above the automatic feeder exchange section 6F. The feeder device 3F to be replenished is placed in one of the storage sections 6F5. The feeder device 3F to be retrieved is placed in the other storage section 6F5. In FIG. 1, the feeder device 3F to be replenished is shown in solid lines, and the feeder device 3F to be retrieved is shown in dashed lines. This is not limited to the above, and the automatic feeder exchange section 6F may run while storing two feeder devices 3F, or may run without storing any feeder device 3F.

The storage section 6F5 has transfer rollers 6F6 arranged in a row in the front-rear and left-right directions. The load of the feeder device 3F stored in the storage section 6F5 is supported by the transfer rollers 6F6. The transfer rollers 6F6 are one embodiment of the replacement side feeder drive section that transfers the feeder device 3F by rotating with the feeder device 3F placed on it. The transfer rollers 6F6 work together with the transfer rollers 29 on the device main body 2 side and the transfer rollers 73 of the height adjustment section 7J described below to transfer the feeder device 3F.

The height relationship between the device body 2 and the automatic feeder exchange unit 6F may change due to the automatic feeder exchange unit 6F traveling back and forth between the parts warehouse 63 and the parts mounting machine 9. For example, the height position of the storage unit 6F5 may change due to changes in the conditions of the travel path 62 and the floor surface F, or due to individual differences between the multiple automatic feeder exchange units 6F. As a countermeasure to this, a height detection unit 7F and a height adjustment unit 7J are provided.

The height adjustment unit 7J is disposed between the automatic feeder exchange unit 6F and the device main body 2. The height adjustment unit 7J consists of a main body 71 and an intermediate storage unit 72 that moves up and down relative to the main body 71. The height position of the intermediate storage unit 72 roughly matches the height position of the feeder holding unit 252 and the height position of the storage unit 6F5 of the automatic feeder exchange unit 6F, and an adjustment range is set in both the up and down directions. The intermediate storage unit 72 temporarily stores the feeder device 3F that passes through in the forward and backward directions.

The intermediate storage section 72 has transfer rollers 73 arranged in a row in the front-rear and left-right directions. The load of the feeder device 3F stored in the intermediate storage section 72 is supported by the transfer rollers 73. The transfer rollers 73 are one embodiment of an intermediate feeder drive section that rotates with the feeder device 3F placed on it to transfer the feeder device 3F.

The height detection unit 7F is disposed on the front surface of the intermediate storage unit 72. The height detection unit 7F detects the height of the storage unit 6F5 that it is generally directly facing. The height detection unit 7F may use the same detection method as the height detection unit 7A of the automatic magazine exchange unit 6A, or a different detection method.

The height adjustment unit 7J raises and lowers the intermediate storage unit 72 based on the detected height of the storage unit 6F5, thereby raising and lowering the feeder device 3F. This eliminates any step in the height direction when the feeder device 3F is transferred between the storage unit 6F5 and the intermediate storage unit 72. Furthermore, when the feeder device 3F is transferred between the intermediate storage unit 72 and the feeder holding unit 252, there is no step in the height direction. This allows for smooth replacement of the feeder device 3F.

Prior to the transfer of the feeder device 3F, the transfer rollers 6F6, 73, and 29 are arranged in a straight line in the front-to-rear direction. The feeder device 3F to be replenished is transferred from the automatic feeder exchange unit 6F to the device body 2 via the height adjustment unit 7J by the forward rotation of the transfer rollers 6F6, 73, and 29. In addition, the lock mechanism of the feeder device 3F to be collected is first released. After that, the feeder device 3F to be collected is transferred from the device body 2 to the automatic feeder exchange unit 6F via the height adjustment unit 7J by the reverse rotation of the transfer rollers 29, 73, and 6F6.

3. Control Configuration of the Tray-type Component Supplying Device 1 Next, the control configuration of the tray-type component supplying device 1 will be described with reference to Figs. 4 and 5. The control device 8 is configured using a computer device having a CPU and operating with software. The control device 8 is provided in the device main body 2, and its installation position is not particularly restricted. As shown in Fig. 4, the control device 8 controls the first lifting mechanism 51 and the second lifting mechanism 52 of the lifting mechanism 5 to select a tray Ty, and controls the shuttle mechanism 4 to execute insertion and removal of the tray Ty.

The control device 8 includes a main body control unit 81 that controls the replacement of the automatic magazine 3A. The main body control unit 81 acquires the detection results from the height detection unit 7A. Furthermore, the main body control unit 81 controls the forward rotation, reverse rotation, and stop of the transfer roller 27. The main body control unit 81 also controls the operation of the first lifting mechanism 51, which serves as a height adjustment unit.

On the other hand, the automatic magazine exchange unit 6A has an exchange side control unit 82 that controls the exchange of the automatic magazine 3A. The exchange side control unit 82 controls the running wheel 6A1 to position the automatic magazine exchange unit 6A at a predetermined exchange position. There are two exchange positions, where one of the storage units 6A5 faces the automatic exchange window 22. The exchange side control unit 82 also controls the transfer roller 6A6 to switch between forward rotation, reverse rotation, and stop.

The main body side control unit 81 and the replacement side control unit 82 exchange control information CA related to the transfer of the automatic magazine 3A via a wireless communication unit (not shown). The control information CA sent from the replacement side control unit 82 to the main body side control unit 81 includes information that the automatic magazine replacement unit 6A has been positioned at the replacement position, information that the sending out of the automatic magazine 3A to be replenished has started, and information that the receipt of the automatic magazine 3A to be collected has been completed.

The control information CA sent from the main body control unit 81 to the replacement control unit 82 includes information that the first lifting mechanism 51 has finished adjusting the height position of the lower holding table 26, information that the sending out of the automatic magazine 3A to be collected has started, and information that the reception of the automatic magazine 3A to be replenished has finished. The main body control unit 81 and the replacement control unit 82 refer to the control information CA exchanged between them to jointly control the replacement operation of the automatic magazine 3A.

The control device 8 further includes a main body control unit 85 that controls the replacement of the feeder device 3F as shown in FIG. 5. The main body control unit 85 acquires the detection result from the height detection unit 7F. The main body control unit 85 also controls the forward rotation, reverse rotation, and stop of the transfer roller 29 and the transfer roller 73. The main body control unit 85 also controls the height position of the intermediate storage unit 72 of the height adjustment unit 7J.

On the other hand, the automatic feeder exchange unit 6F has an exchange-side control unit 86 that controls the exchange of the feeder device 3F. The exchange-side control unit 86 controls the running wheels 6F1 to position the automatic feeder exchange unit 6F at a predetermined exchange position. There are two exchange positions, where one of the storage units 6F5 directly faces the feeder holding unit 252. The exchange-side control unit 86 also controls the transfer roller 6F6 to switch between forward rotation, reverse rotation, and stop.

The main body side control unit 85 and the exchange side control unit 86 exchange control information CF related to the transfer of the feeder device 3F via a wireless communication unit (not shown). The control information CF sent from the exchange side control unit 86 to the main body side control unit 85 includes information that the automatic feeder exchange unit 6F has been positioned at the exchange position, information that the sending out of the feeder device 3F to be replenished has started, and information that the receipt of the feeder device 3F to be collected has been completed.

The control information CF sent from the main body control unit 85 to the exchange control unit 86 includes information that adjustment of the height position of the height adjustment unit 7J has been completed, information that the feeder device 3F to be collected has started to be sent out, and information that the feeder device 3F to be replenished has been received. The main body control unit 85 and the exchange control unit 86 refer to the control information CF exchanged between them to jointly control the exchange operation of the feeder device 3F.

4. Operation of the tray-type component supplying device 1 Next, the operation of the tray-type component supplying device 1 when replacing the automatic magazine 3A will be described with reference to the operation flow of Fig. 6. Prior to the execution of the operation flow, the automatic magazine 3A to be replenished is stored in one storage section 6A5 of the automatic magazine changing section 6A, and the other storage section 6A5 is made empty. Then, the automatic magazine changing section 6A travels to a position near the component mounting machine 9.

In step S1 of FIG. 6, the automatic magazine exchange unit 6A is positioned at the first exchange position. At this time, the empty storage unit 6A5 faces the automatic exchange window 22. In the next step S2, the height detection unit 7A detects the exchange height at which the empty storage unit 6A5 retrieves the automatic magazine 3A. Furthermore, the first lifting mechanism 51 adjusts the height of the automatic magazine 3A to be retrieved based on the detected exchange height of the storage unit 6A5. In the next step S3, the transfer roller 27 and the transfer roller 6A6 operate in conjunction with the joint control of the main body side control unit 81 and the exchange side control unit 82 to retrieve the automatic magazine 3A that was stored in the device main body 2 to the empty storage unit 6A5.

In the next step S4, the automatic magazine exchange unit 6A is positioned at the second exchange position. At this time, the storage unit 6A5, which stores the automatic magazine 3A to be replenished, faces the automatic exchange window 22. In the next step S5, the transfer roller 6A6 and the transfer roller 27 operate in cooperation under the joint control of the main body side control unit 81 and the exchange side control unit 82 to replenish the automatic magazine 3A in the storage unit 6A5 to the device main body 2.

In addition, in the replacement operation of the feeder device 3F, the recovery is performed first, followed by the supply, in the same way, so a detailed explanation will be omitted. However, the height adjustment unit 7J adjusts the height of the feeder device 3F being transferred during both recovery and supply.

According to the embodiment of the tray-type component supply device 1, the automatic magazine exchange unit 6A exchanges the automatic magazine 3A retrieved from the device body 2 with the automatic magazine 3A to be replenished to the device body 2, so that the automatic magazine 3A that contains multiple trays Ty can be automatically exchanged.

In addition, since the manual magazine 3M is used in combination, parts can be supplied from the manual magazine 3M when the automatic magazine 3A is replaced, and the mounting work of the part mounting machine 9 is not interrupted. Furthermore, since the automatic magazine exchange unit 6A travels to the parts warehouse 63, this contributes to labor saving and automation of the parts warehouse 63. In addition, since the tray-type part supply device 1 is equipped with an automatic feeder exchange unit 6F, the replacement of the feeder device 3F can also be automated.

5. Applications and Modifications of the Embodiment The height detection units (7A, 7F) and the height adjustment unit 7J may be provided on the side of the automatic magazine exchange unit 6A and the automatic feeder exchange unit 6F. Also, a configuration in which the feeder device 3F, the automatic feeder exchange unit 6F, and the height adjustment unit 7J are omitted may be adopted. Furthermore, the shuttle mechanism 4 may be used to switch the trays Ty between the automatic magazine 3A and the manual magazine 3M. This reduces the operator's work on the manual magazine 3M.

Also, it is possible to have only the automatic magazine 3A without providing the manual magazine 3M. In this embodiment, the height position of the automatic magazine 3A may be fixed, and the lifting mechanism 5 may drive the shuttle mechanism 4 to lift and lower to select the tray Ty to be pulled out. Furthermore, it is also possible to provide transfer rollers 27 on the upper holding table 28 and the lower holding table 26, and to configure the automatic magazine exchange unit 6A to automatically exchange the automatic magazine 3A for both the upper holding table 28 and the lower holding table 26.

The automatic magazine exchange unit 6A and the automatic feeder exchange unit 6F do not need to be in the form of an automated guided vehicle, and may be stationary.
